Mumbai: Mukesh Ambani and family, who are known for their lavish celebrations during several occasions, went all out when it came to the wedding card of their daughter Isha Ambani who is set to marry Anand Piramal.

The invitation is unique as it is packed inside an elaborately designed storage box, with Isha Ambani's initials etched on the top of it. The actual surprise is revealed when the invitee opens the second box stored inside it.

As the invitee opens the second box, the tune of Gayatri Mantra starts playing. Inside the box are four other small boxes, probably made of gold. Each of these boxes contains a framed picture of Goddess Gayatri.

The invitation comes few days after Mukesh and Nita Ambani announced December 12 as the wedding date of Isha Ambani and her fiancee Anand Piramal.

Isha and Anand got engaged in May and the pre-wedding ritual, God Dhana, was organised at the Ambani residence- Antilla.

Last month, the Ambani family hosted a three-day extravaganza in the picturesque Lake Como in Italy, which was attended by the who's who of Bollywood, among others.

Anand, son of Swati and Ajay Piramal, is the founder of Piramal Realty, a leading real estate firm in India.
